1 Introduction 1.1 The purpose of this Service Level Specification is to document and describe the flood forecasting and warning services provided by the Bureau of Meteorology (the Bureau) in South Australia. 1.2 The Bureau s flood forecasting and warning services are provided within the context of the Total Flood Warning System as defined in the Australian Emergency Manuals Series, Manual 21 Flood Warning (Australian Government, 2009 and illustrated in Figure 1). Figure 1: The components of the Total Flood Warning System (Australian Emergency Manual Series, Manual 21 Flood Warning, Australian Government 2009) 1.3 The Total Flood Warning System recognises that a fully effective flood warning service is multi-faceted in nature and its development and operation involves input from a number of agencies each with specialised roles to play. It is vital that the agencies involved work in close cooperation through all stages of developing and operating the system. The services described here are the Bureau s contribution to the Total Flood Warning System. 1.4 The Bureau s main role in the Total Flood Warning System is focussed on monitoring and prediction, and to a lesser extent interpretation, message construction, and communication components (see Appendix A for descriptions). The Bureau also contributes to review activities and takes a role in the planning and coordination activities associated with ensuring that the activities of all agencies and appropriate linkages are well coordinated. The roles and responsibilities of all key stakeholders involved in the provision of a flood warning 3

service in South Australia are described in the National Arrangements for Flood Forecasting and Warning (Bureau of Meteorology, 2015) 1. 1.5 This Service Level Specification is concerned with describing the Bureau s role in the Total Flood Warning System and its interaction with other stakeholders as described in the National Arrangements. This is to ensure that the service the Bureau is providing in support of each of the relevant components of the Total Flood Warning System is understood by the Bureau and other stakeholders. 1.6 A description of the activities that make up the Bureau s flood forecasting and warning services for South Australia is given in Section 3. This set of activities, associated products and target levels of service constitute the current standard services provided freely by the Bureau. The Bureau also provides supplementary services on a commercial or cost recovery basis but they are not covered in the document. 1 The National Arrangements for Flood Forecasting and Warning (2015) is available on the Bureau s website: http://www.bom.gov.au/water/floods/index.shtml 4

2 Flood Warning Consultative Committee 2.1 The South Australian Flood Warning Consultative Committee provides the Bureau's key stakeholder s with a consultation mechanism for its flood forecasting and warning services. As such, the committee is responsible for reviewing this Service Level Specification on an annual basis or as required. 2.2 The overall role of the South Australian Flood Warning Consultative Committee is to coordinate the development and operation of flood forecasting and warning services in South Australia, acting as an advisory body to the Bureau and participating State and local government agencies. Membership and terms of reference for this committee in South Australia are detailed in Schedule 1. 2.3 The Bureau chairs and provides the secretariat support to the South Australian Flood Warning Consultative Committee, which meets six monthly depending on need and activity. 5

3 Bureau flood forecasting and warning services 3.1 The scope of services covered by this Service Level Specification is confined to those dealing with riverine flooding caused by rainfall where typical rain-to-flood times are six hours or more. Flash flooding (rain-to-flood times less than six hours) and flooding caused purely by elevated sea levels are not covered, nor are the weather forecasting and other services the Bureau provides that contribute to the flood forecasting and warning service, including Severe Weather, Severe Thunderstorm Warnings, Tropical Cyclone Warnings, provision of radar data and rainfall forecasts. 3.1.1 However, a number of locations have been included in Schedule 2 where the forecast lead times are less than six hours due to them being located in the upper reaches of the catchments. 3.1.2 The schedules listing stations being used for flood forecasting and warning include a number of locations which have been installed primarily for monitoring flash flooding by the councils because of their use in enhancing situational awareness and modelling. 3.2 The nature of the services covered by this Service Level Specification include undertaking the routine catchment monitoring and river height prediction activities necessary for the Total Flood Warning System, as well as issuing and publishing specific warning and data products. These activities are listed below with further detail and associated performance measures provided in subsequent sections. Collect and publish rainfall and river level data Routine monitoring of flood potential Flood modelling and prediction Automated information and alerting Issue flood watches Issue flood warnings Communication of flood warnings and flood watches Data networks, communications and storage Operations Publishing of data and flood information Planning and liaison Support for emergency management training and exercises 3.3 Collect and publish rainfall and river level data 3.3.1 The collection and publishing of rainfall and river levels is an important component of the overall service. Apart from use by the Bureau for data analysis and its hydrological modelling for flood predictions, the data is also used by the emergency service agencies, numerous operational agencies, businesses and the public to monitor rainfall and river conditions. To assist in describing the service, the locations where river height; dam, weir or lake level; and tidal observations are made are categorised into three types; namely forecast location (Schedule 2), information location (Schedule 3) and data location (Schedule 4). 6 Forecast location is a location for which the Bureau provides a forecast of future water level either as the class of flood that is predicted (minor, moderate or major) or as a level and class refer to Appendix A for definitions. At these locations observed data, flood classifications and additional qualifying information will also be available (Schedules 2).

Information location is a location at which flood classifications are defined and observations of water level data are provided. At these locations forecasts of future water level are not produced. Other key thresholds may be defined and reported against (Schedule 3). Data location is a location for which just the observed water level data is provided. Flood classifications are not available for these locations and forecasts of future water level are not produced (Schedule 4). 3.3.2 An indicative level of priority has been assigned to each observing site and key communication infrastructure such as radio repeaters (Schedules 2-4 and 7-9) based on a three tiered scheme (Table 1). The priority level was defined by Bureau forecasters based on the expected impact to services. The impacts identified are the expected outcome of a service outage at that site during a flood emergency. Impact is described in terms of forecast performance and the Bureau s ability to provide a flood warning service. Note that the scope of this priority scheme is limited to consideration of the requirements of flood warning only and should not be confused with any other priority assigned to that site by third party owners or other users. Table 1 Site priority Priority Level Impact on performance Impact on service delivery Description High Very difficult to meet target Direct and significant high level impact for the site and/or downstream locations Degradation of service highly likely. Medium Difficult to meet target Some impact for the site and/or downstream locations. Possible degradation of service. Low Not likely to affect meeting targets Little impact on the site and/or downstream location No change in service. Lower possibility of degradation of service. Note: Multiple outages within a given network will lead to a higher impact levels and greater service degradation. Table 1 indicates the effect of a single site failure within an otherwise functional network. 3.4 Routine monitoring of flood potential 3.4.1 The Bureau will maintain an awareness of catchment conditions and monitor the potential for riverine flooding. This monitoring activity will be supported by the Bureau s weather services as required and is an activity undertaken to plan future flood operations. 3.5 Flood modelling and prediction 3.5.1 The Bureau will develop and maintain prediction systems for the forecast locations listed in Schedule 2a. 3.5.2 The Bureau prediction systems can include real-time hydrologic models, simple peak to peak correlations and other hydrologic techniques as appropriate. 3.5.3 The Bureau prediction systems will be maintained and updated following significant events or when new data becomes available. 7

3.5.4 The target level of performance for the prediction at each forecast location is given in Schedules 2a and 2b. 3.5.5 The responsibility for flood modelling and prediction services for the Lower Murray rests with the Department of Environment, Water and Natural Resources (DEWNR). DEWNR s flood forecasting and warning locations are listed in Schedule 2b. 3.5.6 The Bureau s flood modelling and prediction services for locations downstream of SA Water major controlled storages are dependent on communication of release activities to the Bureau. Forecast locations impacted by SA Water dam release activities are detailed in Schedule 2c. 3.6 Automated information and alerting 3.6.1 In South Australia, the Bureau currently provides a threshold-based rainfall and river alarming service for riverine flooding for Torrens, Gawler and Onkaparinga. 3.7 Issue flood watches 3.7.1 The Bureau will issue flood watches when the combination of forecast rainfall and catchment conditions indicates flooding is likely. The catchments and basins covered by flood watches include all those listed in Schedule 10. Note that flood watches may cover catchments that do not have established flood warning services. 3.7.2 The primary purpose of a flood watch is to provide early advice to communities and the relevant emergency service organisations of the potential flood threat from a developing weather situation. Typically, a flood watch is issued 1 to 4 days before an anticipated flood event depending on the confidence in rainfall forecasts. 3.7.3 Flood watches will be communicated by the Bureau using the dissemination methods detailed in section 3.9. 3.8 Issue flood warnings 3.8.1 In general flood warnings are issued based on the following criteria: The river level of at least one forecast location (listed in Schedule 2) is expected to reach and or exceed or has exceeded the minor flood level; The flood classification levels or trigger heights defined at forecast locations are expected to be exceeded (refer to Schedule 2a); The flood class levels defined at information locations are exceeded (refer to Schedule 3). The specific initiating criteria, if any, for each flood warning product is listed in Schedule 10. 8 3.8.2 Flood warnings may include either qualitative or quantitative predictions at forecast locations or a statement about future flooding in more generalised terms as outlined in Table 2. The type of prediction included is commensurate with user requirements, the availability of real time rainfall and river level data, and the capability of available flood prediction systems. A flood warning may contain generalised, quantitative and qualitative predictions and typically start with more generalised information and become more specific as data becomes available as

the event develops and progresses. 3.8.3 Quantitative predictions include expected flood class (minor, moderate or major) with more specific information on the height and time of water levels at the forecast locations identified in Schedules 2a and 2b. A quantitative prediction can be a specific level or a range of levels, and detailed timing down to blocks of a minimum of three-six hours. Quantitative predictions are based on all available information at the time of warning issue. The target lead time of the river height prediction for each forecast location where quantitative predictions are provided is given in Schedules 2a and 2b. For an example of a quantitative prediction refer to Table 2. 3.8.3.1 For the Bureau to be able to provide a quantitative prediction at a location, it is essential to have a suitable network of rainfall and river level sites upstream with data coming in real time, sufficient historical data to calibrate the flood forecasting model, a reliable rating table and documented flood impacts and flood classifications. 3.8.4 Qualitative predictions include expected flood class (minor, moderate or major) and timing of flooding at the forecast locations identified in Schedules 2a and 2b. The timing is indicated in blocks of six, 12 or 24 hours, using the terms such as early morning, afternoon or overnight. Such predictions are based on all available information at that time and may include advice on the peak classification that is expected or has occurred at that location. The target lead time for each forecast location where only qualitative predictions are provided are given in Schedules 2a and 2b. For an example of a qualitative prediction refer to Table 2. 3.8.4.1 For the Bureau to be able to provide qualitative prediction at a location, it is essential to have at least some rainfall and river level sites upstream of the location with data coming in real time, at least some historical flood data to calibrate the flood forecasting model, a reasonable rating table and documented flood impacts and flood classifications. 3.8.5 The Bureau may also issue flood warnings with more generalised predictions and information when there are not enough data to make specific predictions or in the developing stages of a flood. These warnings contain generalised statements advising that flooding is expected and may include forecast trend (rising or falling) (for examples refer to Table 2). 3.8.6 The typical target accuracy of a quantitative water level prediction is that 70% are within 0.3 or 0.6 metres of the observed water level. Specific accuracy targets by location are defined in Schedules 2a and 2b. Achievement of these targets is not possible in all floods or at all locations. In general predictions of a flood peak are more accurate than reach or exceed predictions that are issued during the developing stages of a flood. This is due to uncertainty of future rainfall rates and/or upstream floodplain behaviour that are used when making those predictions. 3.8.7 A list of the flood warnings issued in South Australia, along with the basin/river to which they apply is included in Schedule 10. Details about forecast locations in each basin/river are included in Schedules 2a and 2b. 3.8.8 Flood warning summaries A summary of watches and warnings that are current is provided to help media and other users readily access information. 3.8.9 Schedule 10 includes the River Murray warning product for which flood predictions are provided by the Department of Environment, Water and Natural Resources. 9

Table 2. Prediction type description Prediction type Quantitative Qualitative Generalised Height prediction Numerical prediction - Any Height - Peak Height Can refer to flood class Refers to flood class (minor, moderate or major) No height prediction - forecast trend (rising or falling) Time of prediction More specific, typically in blocks of 3 to 6 hours Range of times (6, 12 or 24 hour blocks) Range of times (24 hour blocks) Example The Gawler River at Gawler West is expected to peak near 8.0 metres (major flooding) about 6pm Sunday. The Onkaparinga River at Verdun is predicted to reach 4.5m (minor flooding) between 2pm and 3pm Friday afternoon. Minor flooding is expected in the North Para River at Penrice during Saturday afternoon. The North Para River at Yaldara is expected to peak above the Major Flood Level during Sunday evening. Flooding is expected in Bremer River at Wanstead Rd during Saturday. 3.9 Communication of flood warnings and flood watches 3.9.1 Flood watches and warnings will be issued directly to a list of stakeholders with emergency management responsibilities. This list is maintained by the Bureau but is not detailed in this document. The direct dissemination methods supported include email, fax and the internet protocols such as File Transfer Protocol (FTP). 3.9.2 The format of messaging in flood related products will conform to a nationally consistent standard determined by the Bureau, in consultation with the Flood Warning Consultative Committee. 3.9.3 Flood watches and warnings are also communicated by the Bureau via: Radio: Radio stations, particularly the ABC, broadcast flood warning information as part of their news bulletins, or whenever practicable. This form of broadcast may be covered in separate agreements between the Bureau and broadcasters. Weather warning service: Flood warning information is recorded on a contracted telephone information service. Calls to this service incur a fee-forservice charge. Internet: Flood watches and warnings are published on the Bureau s public web site and available by File Transfer Protocol (FTP) and Rich Site Summary (RSS) along with related rainfall and river level information (see 3.12). 3.9.4 Emergency management partners 2 and media can also access flood level and warning information directly from the Bureau Flood Warning Centre and Bureau National Operations Centre, subject to operational constraints. The Bureau does not publish contact details for the Flood Warning Centres and Bureau National Operations Centre. 2 Emergency management partners include those organisations that have an emergency management responsibility for the wider community (e.g. State Emergency Services) 10

3.10 Data networks, communications and storage 3.10.1 The services to be provided by the Bureau under this Service Level Specification depend on provision of data from networks of stations owned and operated by the Bureau and partner agencies. Permanent or temporary loss of real time data may necessitate a downgrading of the flood warning service from quantitative predictions to qualitative or generalised. 3.10.2 The Bureau contribution to this network of stations includes: The operation and maintenance of equipment at the sites which are fully owned and maintained by the Bureau as listed in Schedule 7. Assisting with maintenance of equipment for other agencies at the sites listed in Schedule 8. Operating and maintaining Bureau-owned equipment at sites where this equipment is co-located at a site owned by another agency Schedule 9. 3.10.3 Where the site is owned or operated by other parties, installation, maintenance and repairs of Bureau equipment will depend on adequate access being provided to the Bureau and any of its contractors. The Bureau will confirm access arrangements with relevant land owners before entering the premises. The Bureau also requires that the site operators provide timely advice regarding any possible faults or other issues affecting the performance of the data network. 3.10.4 The flood forecasting and warning service for South Australia also depends on the provision of data from partner agency data networks. The provision of these data for each of the agencies concerned is detailed in a Data Sharing Agreement between the Bureau and each partner (Schedule 6). 3.10.5 The Bureau will maintain the essential set of metadata describing the network of stations and related infrastructure regarding the Bureau s component of the data network, along with metadata required to inform the data ingest process for partner agency related networks and sites. 3.10.6 The Data Sharing Agreements are intended to reflect operational arrangements and are not legally binding and allow multiple agreements between individual and/or multiple agencies. 3.10.7 The parties agree to the provision of data as set out in the Data Sharing Agreements during periods of routine site operation and increased frequency during flood periods. 3.10.8 Data transfer protocols and conditions regarding fitness for purpose as provided by each stakeholder will be adhered to as set out in the Data Sharing Agreements for data provision. 3.10.9 The sharing of data as set out in the Data Sharing Agreements can be amended by following the process described in the agreement. 3.10.10 The Bureau has developed special purpose software (Enviromon) for collecting, alarming, storing, on-forwarding and display of data from Event-reporting Radio Telemetry Systems (ERRTS) (field equipment) based on Automated Local Evaluation in Real Time (ALERT) data protocol. 11

3.10.11 The Bureau provides a range of supplementary services associated with Enviromon, including: installation of Enviromon software; the commissioning of an Enviromon base station or maintenance and support; and onsite Enviromon training. However, software licensing and limited support for Enviromon base stations listed in Schedule 5 is currently a standard service (free of charge). 3.11 Operations 3.11.1 The Bureau will use reasonable endeavours to provide a 24 hours a day, seven days a week operational systems capability necessary to support flood warning operations. This will include on-line computer and data ingestion systems, along with appropriate communications infrastructure. 3.11.2 The Bureau operates a regional Flood Warning Centre in each capital city and a Bureau National Operations Centre in Melbourne on an as required basis. 3.11.3 Through the regional Flood Warning Centre and Bureau National Operations Centre, the Bureau will provide operational coverage for up to 24 hours per day during flood events, subject to event requirements and operational constraints. The Bureau will advise its key emergency management clients of any impact in services if it is unable to provide sufficient staff coverage to meet the service levels set out in this Service Level Specification (see also 4.2). 3.11.4 Staff in the Bureau National Operations Centre will support regional operations either remotely or by providing additional capacity to a regional Flood Warning Centre where reasonably possible during significant and long duration events. When necessary, staff from regional offices in areas not impacted by current flooding will endeavour to assist. 3.11.5 The Bureau will maintain an internal catchment directive for each catchment where a warning service is provided. The catchment directive documents and describes the forecast process for the particular catchment and includes flood intelligence information, flood history, contact details for partners with local knowledge and warning issue criteria. 3.11.6 The operation of the Flood Warning Centres will endeavour to be compliant with the fatigue management guidelines developed under the Bureau s Work Health and Safety Procedures. Particular attention to fatigue management will be provided during the management of extreme events. The requirement to comply with these guidelines applies to all personnel present at these centres. 3.11.7 The Bureau will assist in meeting the needs of the Australian Government s National Crisis Coordination Centre. The Bureau will use reasonable endeavours to support and participate in relevant critical event briefings as resources permit. 3.12 Publishing of data and flood information 3.12.1 The Bureau will maintain the systems to ingest all data being gathered through the special purpose flood warning data network. 3.12.2 The river height and rainfall data received by the Bureau will be published as soon as practicable (the data are supplied at different frequencies and by various methods) upon receipt into Bureau operational systems. The data will be published 12

in the form of tables, maps and plots and will also be included in warnings and alerting messages and used in modelling systems. 3.12.3 Data collected in Bureau systems will be available for use by the Bureau as it requires and for distribution to the public on suitable open source licence terms. 3 3.12.4 The Bureau will continue to collect and update the flood background information contained on its website. These include survey information, flood history and flood event reports, catchment maps and brochures. 3.13 Planning and liaison 3.13.1 The Bureau undertakes a range of routine planning, maintenance and liaison activities that support the Total Flood Warning System. This includes contributing to related flood risk management activities within the State or Territory impacting on, or related to flood warning along with the ongoing coordination and liaison activities essential to the smooth operation of the Total Flood Warning System. 3.14 Support for emergency management training and exercises 3.14.1 The Bureau will, within operational constraints, endeavour to support and participate in relevant disaster management activities outside of flood operational periods including training exercises and flood response planning. 3 Please refer to the Creative Commons License: http://www.bom.gov.au/water/regulations/datalicensing/cclicense.shtml 13

4 Level of service and performance reporting 4.1 Achievable levels of service provided by the Bureau are dependent on many factors including adequate access to Bureau equipment where located on sites owned by other agencies, data availability in near real time from Bureau and partner agencies, modelling and prediction capability, geomorphology of the catchment and meteorological considerations such as rainfall patterns. 4.2 If during a flood event the achievable service level is expected to be reduced, for any reason below the target level as stated in this Service Level Specification, the Bureau will inform the key emergency management clients in South Australia of the reduced service level via email and phone. 4.3 The Bureau s performance during significant events will be reviewed and reported on using a standard performance structure developed in conjunction with key stakeholders and within the context of the Total Flood Warning System based on key performance indicators and the service levels defined in Schedule 2. 4.4 An annual performance report will be tabled at a Flood Warning Consultative Committee meeting if significant flooding has occurred in the previous year. This report may be published on the Bureau website. 4.5 Event based performance reports with more detailed technical information may also be produced for significant and high profile events. 14

Appendix A: Glossary of terms A.1. General Bureau Flood Warning Centre: an operational area set aside in each capital city to fulfil the Bureau s role in the Total Flood Warning System specifically flood forecasting and warning. Bureau National Operations Centre: The principal role of the National Operations Centre is to augment regional flood forecasting teams during major floods and to provide operational system support. The National Operations Centre is also responsible for leading new initiatives to enhance the quality of operations and services. Catchment Directive: A catchment directive provides guidance specific to a catchment to help develop forecasting and warning products. Flood warning: A written product to provide advice on impending flooding so people can take action to minimise its negative impact. This will involve some people taking action on their own behalf and others doing so as part of agency responsibilities. Flood watch: A written product that alerts when the combination of forecast rainfall and catchment conditions indicates the flooding is likely. National Crisis Coordination Centre: The Australian Government Crisis Coordination Centre has been designed to connect relevant Australian Government, State and Territory agencies to centralise Australian Government actions during complex national crises, to develop a single, timely and consistent picture or understanding of a crisis, its implications and the national capacity to respond. National Flood Warning Arrangements: The National Arrangements outline the general roles and responsibilities of each level of Government in providing and supporting an effective flood warning service and includes separate chapters describing the specific arrangements and agency roles that apply in each jurisdiction. Protective behaviour: generating appropriate and timely actions and behaviours from the agencies involved and from the threatened community. Severe Thunderstorm: A thunderstorm is characterised by sudden electrical discharges, each manifested by a flash of light (lightning) and a sharp rumbling sound. Thunderstorms are associated with convective clouds (cumulonimbus) and are usually accompanied by precipitation. Thunderstorms are often short-lived and impact on only a small area. Severe thunderstorms may last for an hour or more and can have a more widespread impact. A severe thunderstorm will also have one or more of the following phenomena: Tornado Wind gust of 90 km/h (49 knots) or more Hailstones with diameter of 2 cm or larger Very heavy rain sufficient to cause flash flooding Weather warnings: Weather warnings are messages sent out by the Bureau to warn the community of potentially hazardous or dangerous weather conditions. Such warnings include but are not limited to: road weather alerts, severe thunderstorm warnings, severe weather warnings for heavy rain, strong or gale force winds, marine wind warnings, warnings for sheep graziers and frost warnings. More information on weather terms is given in the Bureau's glossary. A.2. 38 The Components of the Total Flood Warning System

Based on the Manual 21 Australian Emergency Manual Series, Australian Government 2009 (see the Manual for more details). Communication: disseminating warning information in a timely fashion to people and organisations likely to be affected by the flood (see Chapter 6). Interpretation: identifying in advance the impacts of the predicted flood levels on communities at risk (see Chapter 4). Message construction: devising the content of the message which will warn people of impending flooding (see Chapter 5). Monitoring and prediction: detecting environmental conditions that lead to flooding, and predicting river levels during the flood (see Chapter 3), Review: examining the various aspects of the system with a view to improving its performance (see Chapter 7). A.3 Flood classifications The classification of minor, moderate and major flood levels at key river height stations is based upon the effect of flooding for some distance upstream and downstream of that station. These levels are determined using the following descriptive categories of flooding, historical data or relevant local information. The process for establishing flood class levels involves determining local flood effects, review and endorsement by relevant stakeholders and passing recommendations to the Bureau for inclusion in forecast and warning procedures. The process for establishment of flood class levels specific to each State and Territory is documented in the National Arrangements. Minor flooding - Causes inconvenience. Low-lying areas next to watercourses are inundated. Minor roads may be closed and low-level bridges submerged. In urban areas inundation may affect some backyards and buildings below the floor level as well as bicycle and pedestrian paths. In rural areas removal of stock and equipment may be required. Moderate flooding - In addition to the above, the area of inundation is more substantial. Main traffic routes may be affected. Some buildings may be affected above the floor level. Evacuation of flood affected areas may be required. In rural areas removal of stock is required. Major flooding - In addition to the above, extensive rural areas and/or urban areas are inundated. Many buildings may be affected above the floor level. Properties and towns are likely to be isolated and major rail and traffic routes closed. Evacuation of flood affected areas may be required. Utility services may be impacted. 39
